Good review in Variety
But if the conceit is unoriginal, its familiarity works to the comedy's advantage. Fairly hopeless Kate (Jessica Hynes), who has organized the gathering at a renovated priory in the middle of nowhere, observes to architect Daniel (pin-sharp Joseph Millson) that this isn't going to be a big drunken party: "A few friends. People we like. No craziness." But her statement clearly is so far off the mark, it sets up an amused ripple of anticipation.
While The Independent can't recommend it highly enough.
The critics have been slightly sniffy about this production (too much fun: not enough substance is the subtext) but this is the very best sort of adult pantomime. You laugh, you cry, you scream. (There's definitely something behind you, and it's wearing a dark hood.)
Where else are you going to see a play where a Bafta-winning head of Children's BBC TV gets off her head on valium and cocaine. And, frankly, you're on her side.
